This makes me a bit unhappy. I put in a new gas level sending unit in 2014. I started having problems about 18 months ago, but thought it was the gauge. After all, the gauge was 55 years old and the sending unit was only 3 years old. I sent the gauge in and had it repaired (Western Instruments are great!), but I still had problems. I did multiple tests and even bought a new vom.

I really, really didn't want to drain my gas tank. Such a PITA to drain it out and then worse is trying to reseal it so it doesn't leak. Everything concerned is just a big hassle, not to mention I had to buy two new 5-gallon gas jugs, drain hose, and a catch pan which all came to about $40. Plus screwing around with purchasing a new vom, because the problem couldn't possibly be a 3 year old sending unit, right?

After a lot of expense and a lot of time testing, I decided to button things up, because I was going on a vacation and didn't want to leave the gas tank open. As I was slipping the float through the hole, I noticed a small bubble. Yeap, the float is so perfectly full of fuel that it is nearly imperceptible. I would never have known had it not been for that one tiny bubble.

The part that disturbs me is that after all I have purchased from Moss (nearly 100% of everything to restore my car), the most slack they would cut me on a new sending unit was to knock the price down from $56 to $47. Hardly seems fair regardless if it is out of warranty. Obviously, its not a problem I caused. I'm mildly pissed off.

You're right, Wyatt... Just discovered and new complete sending unit is on the way. Would you believe I couldn't just get the float? I have some copper and considered making my own. Super, super po'ed.....

A lot of people have had this problem in recent years. The wire loop at the end of the float arm puts pressure on the molded plastic float seam and the seam cracks letting fuel in. Poor quality float ! You can get a replacement float made of solid closed cell plastic with a brass sleeve with a grove for the loop at the end of the float arm. They cost $6 or $7. I got mine from Summit Racing, Think they are made by Stewart Warner. Dave

Hey, thanks guys! I have cancelled my order at Moss. At least, I hope I have -- they were trying to track it down so it didn't go out. I hope they are successful. I don't want to get even more money tied up into something that I thought should have had a better option from Moss other than "buy a totally new sender".

You can also get a Ford Mustang float (brass / copper??) for about $6.

Check the very tip of the gauge unit float arm where it wraps around the float. I think they just cut these with snips, leaving a sharp burr that will cause a hole in the float. File this area down to eliminate sharp points.
